Beer pipe circulation cleaner



March E3, 1934 MHQHAELSEN 11 9511252 BEER PIPE CIRCULATION CLEANER FiledMay 8, 1933 INVENTOR ATTORNEY Patented Mar. 13, 1934 Nl'i'D STATESPATENT OFFICE 1 Claim.

The main object of this invention is to provide a cleaner for cleansingdraught beer circulatory systems. My device uses a sponge which isintroduced into the apparatus and circulates entirely through the beerdraught circulation system and the device with a constantly movingcolumn of water.

Another object of the invention is to provide a beer pipe circulationcleaner which is inexpensive in cost of manufacture and simple indesign.

The above and other objects will become apparent in the descriptionbelow in which characters of reference refer to like named parts in thedrawing.

Referring briefly to the drawing Figure 1 is a front elevational view ofthe beer pipe circulation cleaner showing a section of the sight glassbroken away to expose the slime removing sponge.

Figure 2 is a side elevational view of the device.

Figure 3 is a top plan view of the device.

Figure 4 is a cross sectional view through the valve body showing thevalve in position for deflecting and reversing the column of waterpassing through the device.

Figure 5 is a cross sectional view through the valve body, the sectionbeing taken on line 5-5 of Figure 4.

Referring in detail to the drawing, the numeral indicates a baseboardupon which the entire device is mounted. Superimposed over thisbaseboard is a valve body 11 in which a valve stem 13 is located. Thisvalve body is provided with substantially intersecting passageways 14,15, 16, 17. The passageways 15 and 17 have sleeve members 12 and 18leading to them. From these sleeves reducer elbows 19 and 20 extend. Thelower smaller ends of the elbows depend downwardly and have triangularflanges 21 secured thereto. These flanges 21 superimpose similar members22 which latter are spaced apart from the upper members and securebetween them transparent glass sighting members 23. The flange members21 and 22 are secured mutually by tie rods 24 on the latter of whichthreaded ends are provided to which nuts 25 are engaged.

The passageway 14 serves as the inlet in the valve body and all of thepassageways have threaded recesses 25. The upper end of the passageway14 receives the smaller end of a reducer elbow 26 from which a taperedinlet nozzle 27 extends horizontally. The passageway 16, aligned withthe passageway 14 and also provided with a recess in which threads areformed is similarly providedwithareducer elbow 28 to which a secondelbow 29 is secured. This latter member 29 has a depending outlet nozzle30 extending therefrom.

Below the transparent glass sighting members 23 reducer elbows 31 arecoupled and have horizontal circulation nozzles 32 secured to theirouter ends.

The valve stem 13 is substantially tapered to make a leak proof fltbetween the valve body and the valve stem, and is provided with a pairof oppositely disposed diametro channels 33 and 34. These latterchannels deflect the water circulating through the system and cause saidwater to by-pass from the passageway 14 into the passageway 15, and fromthe passageway 16 into the passageway 1'7.

It should be noted that a sponge of spherical proportions and indicatedby the numeral 35 is introduced into the circulation of the device andalso the hose sections 36 and 37 which are coupled to opposing ends of abeer pipe coil. This sponge may be of rubber or an abrasive member suchas a floating stone of the petrified variety may be introduced. Theobject of introducing the sponge or abrasive member 35 into the systemis to cleanse the slimy material and sediment from the interior surfaceof the coil and remainder of the beer pipe circulation system to whichthe device is tempora 'ly coupled for purposes of cleaning. I placeemphasis upon the fact that the entire channel passageways and sightingcolumns including the elbows and nozzles are of the same gauge and noshoulders or recesses of any kind are introduced into the organizationby reason of this design, so that the sponge will have free and readytravel through the cleaning device and through the coil 38, thecleansing of which is the goal.

It is to be noted that certain changes in form and construction may bemade without departing from the spirit and scope of the invention.

The valve stem is provided with a square shank 39 upon which a handle 40is secured, a lug 41 on the valve handle cooperates with a similar lug42 on the valve body, the latter serving as a stop for the rotation ofthe handle 41.

I claim:

In a beer pipe cleaner an elongated upright valve body, an upper inletand a lower outlet extending from said valve body, sleeves projectingfrom opposite sides of said valve body and in communication with theinterior thereof, elbow fixtures depending from said sleeves, saidelbows having reduced ends, sighting glasses extending downwardly fromthe reduced ends of said elbows, a pair of oppositely disposedcirculation a lug extending from the secured end of said handle beingadapted to co-operate with the lug on the valve body to limit rotationof said valve handle and valve stem, said beer pipe cleaner beingadapted. to have means introduced therein to frictionally and abrasivelyremove the sediment from the c0i1s of a beer pipe circulation systemsHENRY MICHAELSEN.
